Komatsu D37

jeudi 25 septembre 2014

i recently ran a D37 for a few hours and had a few questions. I've been looking at these for sale and am confused on the series lettering. They are showing D37ex and D37px. Some also 21 and 21A. Just wondering what the differences are in these machines. I'm assuming one has something to do with long track or short track. Thanks
